Unfortunately, I think your math is a little off...
$3,200,000,000,000 ÷ 300,000,000 = $10,667 per person per year*
(which is really closer to $9,756 per person per year since our population is closer to 328M)
But like
@methodical said, we're currently spending around $3.4T per year on health care, so switching from the status quo to Bernie's plan would actually collectively save us around $200B per year, which equates into $610 per person per year. More coverage for less money? In theory, the vast majority of Americans should be on board with this idea. But we all know that's not going to happen...
